A/C control head on Toyota 4Runners gets replacement bulbs

Toyota reports that the a/c control head on some 2003-09 4Runner SUVs may flicker or dim during vehicle operation.

In some cases, the panel may actually go out altogether, only to mysteriously return a few minutes later. The Japanese carmaker attributes the trouble to the two bulbs that provide the illumination for the control head.

Installing upgraded bulbs, Part No. 90010-09017, should eliminate the annoyance.
